- ATTORNEY UNITED-STATES NELSON B. HENRY, or

, orn-nxrnnssrn'el CAGE 1 Ann rnnss;

T all whom it may concern a citizenof the United Staes, residin at Atlanta, in the county of Fulton and tate of Georgia,.have invented certain new and useful Improvements in Oil Expressing Cages and Presses, of which the following is a specification. v

My invention has relation to oil-expressing cages and presses especially adapted for the extraction of oil from cotton seed cake or the like.

My present invention has for its object the provision of a cage adapted for the re- 7 press. 1

ception of a plurality of superposed oil cakes, and constructed with a plurality of superposed plates arranged to receive and properly conduct off the oil from the expressed cakes, said cage being so constructed and so arranged with respect to the oil press that the cage with its cakes may be readily inserted in or removed from the press as occasion requires. I g

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which- 7 Figure 1 is a side elevation of a press arranged to receive the cage embodying my invention.

Fig. 2 is a plan view of the base to -receive the cage, said base constituting an oil chamber. v

Fig. 3 is a plan view of the bottom ofthe Fig. 4: is a top view of the bottom frame of the cage. i I l Fig. 5 is a side elevational view of the cage removed from its oil receiving base and from the press.

Fig. 6 is a vertical sectional view illustrating in detail the arrangement and construction of the cage, and

Fig. 7 isa. detail perspective view of a portion of one of the plates constituting the cage.

' Referring to the drawings, the press has the usual hydraulic piston 1 and cylinder 2, and the top block 3 supported from the upper frame 4, the cylinder frame 5 and upper frame 4: being united by the usual standards 6. r

On the lower frame 5 is supported the two parallel L beams or angle pieces 10' JTILANTA," enoRGIA,-l ssIeN'0R- 'ro inn munnavacoivrrnny; h i; or DALLAS, crnxas a c'onroaa'rronor-.r-nxas. i; I

-forming rails" for the-reception Be it known that ILNELSON B; HENRY,

ance 'of the'box 7 constituting the base and oil collecting su'pport for the, cage; I The" box has the ralledged aperture 8 for' the passage of the piston l and'the ledge or 9 adapted to be advanced by the piston into and through the cage, to force'thecakes, in sa d cage, upward against the stationary block 3 of the press. The box 7 has a pipe rior' may be discharged." The lugs 12 on the box are .for a purpose not necessary to explain n the present patent. I

Referring now to Figs. 4 to 7, the cage consists of aplurality of rectanglar frames v application. for

6- rim of thea-perture supports a follow blocli 11 through which oil c'ollectingin its inte- I 13 superposed upon each other and assembled between an upper and lower frame 14 1 V plate (see Fig. 4) has apertures 18: discharging her 7. i 1

apertures 17 a horizontal channel. "18 the inner wall of which tapers or is beveled upward to form a lip 19. This lip 19 of one frame 13 forms with the fiat base of an adjacentlsuperposed frame 13,-01' with the into the boX-oroil collecting chamv V a I Q Each frame 13 has adjacent to each set of a base of the uppermost frame 1 1', a thin opening or slot into the interior of the cage. This thin openingor slot permits of j the passage of oil from the pressed cakes into the gradually enlarged channels 18 and thence into the vertical apertures 17 and to the box 7.

jects of my invention,- what I claim as new and desirefto secure by Letters Patent is+ 1. A press cage made 1up-ofa plurality, of frames each having a multiplicity of perforations from one side or face of each" .frame to the other, and a groove around the inner facial margin of the framereaching from the margin to the perforations f the frames arranged face toface so that Having thus described thenature and ob 7 said perforations form registering oil con- I duits traversing the frames and'the cage,

the grooves, when the framesare fitted together, forming slots between the faces of adjacent framesyleading from the" interior of the cage to theregistering conduits;

means to hold the assembled frames in true relation to form a cage. r

2. A press cage made up of a plurality" of frames having a multiplicity of perfo to the other registering With the perforathe frame reaching, with gradually increasing depth; from the margin to the perforations; the frames arranged face to face so that said perforations form registering oil conduits traversingthe frames and the cage,

the grooves When the frames are fitted together' forming slots, expanding inivard; from the interior of the cage to the register ;1ng conduits; means to hold the assembledframes in true relation to form a cage.

3. A press cage framehavmg a multiplicity of perforations'from one side'or face of eachj'frame to the other and having a groove around the inner facial margin of the frame reachlng-from the margin to the perforations.

In testimony whereof I have Signedmy name to this specification.
